I.2. Selective Computation

There is a set of special objects that, when encountered in an object calculation, are not treated as described in the previous section. These objects are described in the following sections. For each of them, a selective list of entries is chosen, and only the value of the entry is digested; the key is not included.

When the transform method is DocMDP (see “DocMDP” on page 690)or UR (see “UR” on page 692), the object digest is computed over the entire document (see Section I.2.1, “Document”). The calculation varies depending on the transform parameters, which may specify, for example, whether form fields or annotations are included.
